GHD | Oceana Gold New Zealand Ltd. | 12552081 | Waihi North Project 69 Figure 51 Predicted zinc concentrations at OH6 over 2027 6.3.8 LOM Ohinemuri River Water Quality The water quality is expected to vary throughout the LOM and be closely related to the development of Waihi North. The LOM predictions for iron and cyanide are illustrated in Figure 52 and Figure 53 respectively. The increasing iron concentrations are closely tied to the development of WUG whereas the predicted WAD cyanide concentrations are more closely tied to the ore processing volumes and tailings development.
